EmmyMiao87 opened a new pull request #6018:
URL: https://github.com/apache/incubator-doris/pull/6018
## Proposed changes
QueryDetail is used to statistic the current query details.
This property will only be set when the query starts to execute.
So in the query planning stage, using this attribute in the first query will
cause 'NullPointerException'.
After that, this attribute retains the value of the previous query
until it is updated by the subsequent process.
Because code of 'colocateagg' uses this attribute incorrectly in its
planning,
it causes 'NullPointerException' when clients like pymysql connect to
doris and send the first query.
Fixed #6017
